1 claim. l

This invention relates to pipe fittings and more particularly to a ttingadapted to be axially slidable in and out of a pipe to locate the spigotat different extended positions and wherein the slidable fitting can berevolved to position the spigot to different angles for extending theflow of water or other liquid (or gas).

It is an object of the present invention to provide an adjustable pipefitting which will be slidable in and out of a larger pipe and alsorotatable there within and which is of simple construction, inexpensiveto manufacture, water-tight, and enicient in operation.

For other objects of the invention and for a better understanding of theinvention, reference may be had to the following detailed descriptiontaken in connection with the accompanying drawing, in which Fig. 1 is afront elevational view looking upon the spigot end of the fitting,

Fig. 2 is a side-elevational view of the extended pipe, the fitting, andthe spigot,

Fig. 3 is an enlarged cross-sectional view taken on line 3-3 of Fig. 2,and looking in the direction of the arrows thereof.

Fig. 4 is a fragmentary cross-sectional view taken through a modifiedform of packing gland,

Fig. 5 is a fragmentary cross-sectional view of still another form oftop packing gland.

Referring now to the gures, I represents a water pipe having a T-ttingII from which is extended a pipe I2 which is threaded as indicated at I3to receive a sleeve fitting I4 having a radially inwardly extendingportion I to serve as a guide for an axially adjustable pipe I6 and as asupport for packing material I1 vwhich is retained in place by a sleevefitting I 8 threadedly connected to the top of the tting I4. The pipe I6is also adjustable through the sleeve I8 and has an outwardly flared endI9 which will abut the radially inwardly extending portion I5 of thesleeve I4 to limit the outward movement of the pipe I6.

The top of the pipe I6 is threaded and receives a pipe coupling 2I towhich a spigot 22 is connected. The pipe I6 will be retained in itsretracted position by a spring portion 22 engaging with the top of thecoupling 2I and fixed to a sleeve nut 23 threaded upon the top of thesleeve I 8 to retain a packing 24. It will be apparent that by the useof a double packing arrangement there is little opportunity for leakage.The pipe I6 can also be rotated within the arrangement so as to directnozzle 25 of spigot 22 in any direction to render the same more suitablefor the attachment thereto of a hose coupling.

Referring now particularly to Fig. 4, an internal nut 26 is used forsecuring packing 21 within an internally threaded sleeve 28. The pipe I6is slidable through this packing gland. In Fig. 5 gland 21 is retainedin place by a plate 29 fitted over studs 3I in a sleeve 32 and securedthereto by nuts 33.

Having now described my invention, I claim:

In extensible piping, the combination of an outer pipe having one endprovided with a portion adapted to form :a part of a sealed joint, asleeve fitting having a bore provided with end portions adapted t0 formparts of sealed joints, one of said end portions of said sleeve fittingbeing joined and sealed to said outer pipe end portion, an annularshoulder intermediate the ends of the bore extending radially inwardlythereof, a sleeve joined and sealed to the remaining end portion of saidsleeve tting, a sleeve nut threaded on said sleeve, an inner pipetelescoping within said outer pipe and slidably guided by said annu- 25lar shoulder, an outwardly flared portion terminating the inner end ofsaid inner pipe, said flared portion being adapted to abut said annularshoulder to limit movement of said inner pipe outward of said outerpipe, a pipe coupling attached to the outer end of said inner pipe, saidpipe coupling being adapted to abut said sleeve nut to limit movement ofsaid inner pipe inwardly o said outer pipe, spring latch means attachedto said sleeve nut and adapted to engage said pipe coupling whenadjacentsaid sleeve nut to retain said inner pipe in retracted position,a packing means retained between said sleeve nut and sleeve and inuidtight slidable guiding relationship about said inner pipe and apacking means -retained between said sleeve and annular shoulder and influidtight slidable guiding relationship about said inner plpe.
